From publisher blurb:
The Advanced Edge is a companion sourcebook to The Advanced Arsenal and The Advanced Armory. The Advanced Edge focuses on futuristic melee weapons, as well as muscle-powered ranged weapons.
In addition to futuristic weapons, some relatively lowtech weapons from exotic cultures are introduced, as many of these exotic cultural weapons are wielded by the heroes and villains of Otherverse Games’ signature campaign worlds.
This sourcebook also standardizes and collects a wide variety of exotic and ultra-tech melee weapons originally presented in several different sourcebooks and campaign worlds, and consolidate their information in one place, in one format.
